This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SU in place of this model. The replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 30mm stroke, G1/4 ports and a fixed rubber bumper. Air drives the push (work) stroke and the spring returns the rod — it rests retracted on air loss. This model is discontinued; the drop-in replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SU
The AirTAC MSAL40X30SU is a discontinued 40mm single-acting push cylinder with a 30mm stroke. Air extends the rod while an internal spring retracts it, providing a fail-safe retracted home on air loss. It delivers 539.9 N of usable push force at 0.5 MPa. The exact drop-in replacement is the MSBL40X30SU, matching the bore, stroke, G1/4 port, and U flat-end back cover.
This SKU includes the -S magnet for position sensing. The MSAL uses older CS1-M or DS1-M reed switches, whereas the MSBL replacement takes CMSG, DMSG, or EMSG sensors. The MSAL features threaded covers and a fixed rubber bumper, while the MSBL upgrades to a riveted rolling-packed body. Minimum working pressure is 0.2 MPa to overcome the return spring.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SU |
| Bore size | Ø40 mm |
| Stroke | 30 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 150 mm |
Single-acting minimum working pressure is 0.2 MPa (the air must overcome the return spring). Do not apply an external load during the spring return stroke. The AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SU carries the same single-acting ratings.
Usable Push Force (Ø40mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 539.9 N |
| 0.7 MPa | 791.1 N |
Usable single-acting force after the return spring — lower than a same-bore double-acting cylinder. Size with a margin.

Where the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SU Is Used
Punch Press Ejection
Ejects stamped metal parts from a 40-ton press bed using 539.9 N at 0.5 MPa, with the spring ensuring the ejector retracts clear before the next hit.
Injection Mold Core
Pushes a mold core pin forward to form a plastic boss, relying on the U flat-end back cover to absorb the 791.1 N peak injection force at 0.7 MPa.
Pallet Stopper Gate
Acts as a spring-return stop gate on a packaging conveyor, blocking 40mm tall pallets and safely dropping out of the way on air loss.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SU
Replace this MSAL40X30SU directly with the MSBL40X30SU. Confirm the 40mm bore, 30mm stroke, PT G1/4 port, M12x1.25 rod-end thread, U flat-end back cover, and -S magnet (noting your sensors will change from CS1-M/DS1-M to CMSG/DMSG/EMSG). Ensure your air supply beats the 0.2 MPa minimum, and apply no external load on the spring return stroke for safety.
To size either way: stepping down to the 32mm bore drops the 0.5 MPa push force to 317.7 N, while stepping up is unavailable as 40mm is the largest MSAL bore. The 30mm stroke is well below the 150mm maximum, keeping rod bending stress minimal even under high 791.1 N peak forces at 0.7 MPa.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SU (same bore/stroke/force)
- ✓ Same push direction and retracted fail-safe home
- ✓ Min 0.2 MPa; no external load on the spring return
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa (min 0.2 to overcome the spring).
- check Apply no external load on the spring return stroke.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SU FAQ
Yes, the MSAL40X30SU is discontinued. The exact drop-in replacement is the MSBL40X30SU, which matches the 40mm bore, 30mm stroke, G1/4 port, U back cover, and -S magnet. You will need to upgrade your position sensors from the old CS1-M/DS1-M to the new CMSG/DMSG/EMSG family.
This single-acting push cylinder provides 539.9 N of usable push force at 0.5 MPa and 791.1 N at 0.7 MPa (equivalent to roughly 80.6 kgf). It requires a minimum 0.2 MPa operating pressure to overcome the internal return spring, operates at 50-800 mm/s, and uses a fixed rubber bumper since it lacks adjustable cushions.
